I have Joomla 1.0.13 hosted at HostGator. I wanted to use PHP5 for extra security layer.

HG use PHPSuEXEC

I have this line in .htaccess: AddHandler application/x-httpd-php5 .php

The end result is that the home page index.php registers a 404. All other pages are working fine.

I don't have a problem if it's in php4 so am wondering just how important PHP5 is vs. PHP4.

Thank you for advice.
